Use system recommendations to introduce security
Introduction & Best Practices
The permissions in the NWBC are handled as well as in the normal SAP Easy Access menu. For example, you can assign transactions and Web Dynpro applications to the individual and collection roles in a defined menu structure in the Role menu. The navigation structure of the NWBC reflects the menu structure and settings of the corresponding PFCG role assigned to the user. The folder structure of the Role menu directly affects the navigation bar that is displayed to the user in the NWBC.
In addition, you can also define customised permission checks in the SOS and also define combinations of authorization objects and their values. You can create up to 1,000 custom permissions checks in the Check ID namespace 9000 to 9999. You can also redefine whitelists for these permission checks, which apply to either individual or all of the customer's permission checks. The configuration is described in SAP Note 837490.
Permissions and User Root Sets Evaluations
Once you have identified the organisational features to consider, verify that you can redesign the existing roles so that the organisational features can be clearly maintained by use. This leads you to a concept in which functional and organisational separation is simply possible. However, it will end up with a larger amount of roles: Roles posting/investing, changing roles, reading roles. Such a concept is free of functional separation conflicts and is so granular that the organisational characteristics can be pronounced per use area.
So much information... how can you keep it so that you can find it again when you need it? That's what Scribble Papers is great for.
In order to use the statistical usage data, you must first extend the default SAP value of the retention time to a reasonable period of time. For a representative period, a minimum of 14 months and a maximum of 24 months shall be sufficient. This includes day-to-day business, monthly financial statements, underyear activities such as inventory and annual financial statements. Now call the transaction ST03N and navigate to: Collector & Perf. Database > Performance Database > Workload Collector Database > Reorganisation > Control Panel.
The possibility of assigning authorizations during the go-live can be additionally secured by using "Shortcut for SAP systems".
Transport Recording for profiles of modified rolls: Allows you to have the modified profiles written to a transport order.
This means that authorizations are no longer assigned generally, but only for the objects in the authorization profile.
